- Direct communication with the developer

Working remotely with a developer in India
UK working hours shift against India when the UK changes between standard time and daylight saving. We agree a practical call window and use written updates between calls. We agree the project scope, response expectations, payment terms and handover in writing before work begins. Any local payment, shipping, language, privacy or compliance requirements must be specified by your team; I implement agreed technical requirements and do not provide legal or tax advice.
Milestones and handover
A feasibility review should establish supported devices, platform distribution, authentication, API dependencies and release ownership. Native iOS or Android delivery is not assumed; the platform and my technical fit are confirmed before a commitment. The final handover lists completed work, any agreed follow-up items and the access or documentation your team needs to operate it.
What to include in your brief
Share the target devices, required app-store platforms, core user tasks, backend or API, offline needs and any existing mobile app. Share your Mobile app development goals, current platform or systems, target users, required integrations, preferred time zone and target date. You receive a scope and quote before development starts, and we review progress against agreed milestones.
